20V Max Backpack Sprayer Specifications

Top 10 Customer Questions & Answers – 20V Max Backpack Sprayer

Q1: Does this sprayer come with a battery and charger? A: No, this is a "Tool Only" unit. It does not include a battery or a charger. You will need to use your existing standard DeWalt 20V MAX Lithium-Ion battery to operate it.

Q2: Will my DeWalt 20V/60V FlexVolt battery or 6.0Ah battery fit in the compartment? A: No, they will not fit. To protect the battery from moisture and dust, the unit features a fully enclosed and sealed battery compartment. It is specifically designed to fit standard DeWalt 20V MAX batteries up to 5.0Ah (such as DCB200, DCB203, DCB204, and DCB205). Larger capacity batteries (6.0Ah+) and FlexVolt batteries are physically too bulky for the protective lid to close and lock securely.

Q3: How should I clean the sprayer after using fertilizers or other solutions? A: Proper maintenance is crucial for maximizing the lifespan of the diaphragm pump and seals. After each use, you must never leave solutions sitting in the tank overnight. Please empty the tank completely, then fill it with up to 4 gallons of clean water. Run the sprayer to flush the clean water through the pump, hose, and wand. Repeat this flushing process 2 to 3 times to ensure all residue is completely cleared out and to prevent future clogging.

Q4: How far can this sprayer shoot? I need to reach the second story of my house and tall trees. A: When adjusted to the maximum 90 PSI high-pressure setting, the sprayer can reach up to 20–25 feet vertically. This makes it highly effective for spraying tall tree canopies, second-story siding, or high windows without needing a ladder.

Q5: How long will a standard 5.0Ah battery last on a single charge? A: A fully charged 5.0Ah battery provides up to 2.5 hours of continuous spraying. This allows you to spray over 100 gallons of liquid (approximately 25 to 30 full 4-gallon tank refills) before needing to recharge, making it perfect for large properties.

Q6: Is the spray pressure adjustable, or is it just one speed? A: It is fully adjustable! The unit features a variable pressure dial that allows you to smoothly adjust from 0 up to 90 PSI. You can instantly dial it down for a gentle mist for delicate greenhouse plants, or turn it up for a high-pressure stream to clean siding and decks.

Q7: Can I use wettable powders or harsh solutions in this tank? A: Yes. The sprayer is equipped with a heavy-duty Diaphragm Pump, which is much better at handling wettable powders without clogging compared to standard gear pumps. It also features premium Nitrile/FKM seals and a UV-protected tank that safely handle standard liquid fertilizers, plant nutrients, and water-soluble solutions. (Note: Flammable liquids should never be used).

Q8: What kind of nozzles does it come with? Is the wand made of plastic? A: The wand is made of non-corrosive, heavy-duty stainless steel (telescoping from 21 to 40 inches). The sprayer includes 5 specialized nozzles to cover all applications: a Butterfly Single-head, F-type Dual-head, Three-shower, Five-hole, and a Copper Nozzle. It also features a universal connection for aftermarket attachments.

Q9: How heavy is this backpack when completely full of water? A: Four gallons of liquid weighs approximately 33.4 lbs. Combined with the dry weight of the machine and the battery, the total weight will be around 43–45 lbs when fully loaded. However, our pro-grade deluxe harness—featuring a breathable mesh back pad, wide padded shoulder straps, and an adjustable hip belt—helps distribute this weight evenly across your body to significantly reduce fatigue.

Q10: Do I have to manually pump this at all like traditional sprayers? A: Not at all. This is a fully automatic, battery-powered electric sprayer. The 40W electric motor and diaphragm pump do 100% of the work. Just squeeze the handle and spray, completely eliminating the arm and shoulder fatigue associated with traditional manual pump-action backpack sprayers.
